AI Technical Summary

Benefits of technology

The method produces thaumatin compositions with enhanced sweetness, umami, or flavor masking capabilities, allowing for tailored properties without introducing noticeable sweetness or altering the natural origin of thaumatin, thereby improving organoleptic performance and reducing the need for high thaumatin levels.

Problems solved by technology

However, the traditional naturally-derived sweeteners, particularly sucrose, suffer from the major drawbacks that they are high in energy content (“high in Calories”), leading to a risk of obesity and associated health problems.
However, many of the products developed have proven to have undesirable properties, such as aftertaste, mouth feel or dietary intolerances amongst a substantial proportion of consumers.
Additionally, to be as sure as possible that an artificial sweetener is safe (particularly in long-term use) requires lengthy and expensive testing.
Thaumatin is not a complete replacement for sucrose, however.

Embodiment Construction

[0052]Embodiments of the present invention will now be more particularly described by way of example.

[0053]The existing process for extracting thaumatin and producing commercially-usable compositions comprising thaumatin generally has the following sequence of steps.

[0054]Excision of arils of the fruit of Thaumatacoccus danielii: the Katemfe fruit is not a true “fruit”, but comprises the “aril”, a fleshy sac covering or attached to each seed (more familiar examples may be the edible “seeds” of the pomegranate, or the so-called yew “berry”). Thaumatin is naturally secreted in the aril, and there are well known cultivation techniques to produce high and reliable thaumatin levels therein.

[0055]Rapid freezing of discrete excised arils, followed by bulk freezing for transport and cold storage of the arils.

[0056]The first extraction step is an aqueous “mashing” of the arils, which is followed by a primary filtration of the mash liquor.

[0057]Caustic treatment of the filtered liquor compris...

Abstract

The present invention relates to processes for preparing compositions containing thaumatin having desired properties. More particularly but not exclusively, it relates to compositions containing thaumatin having particular organoleptic properties, and to processes for their manufacture.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Patent Application No. 61 / 449,951, filed Mar. 7, 2011, the entire contents of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to processes for preparing compositions containing thaumatin having desired properties. More particularly but not exclusively, it relates to compositions containing thaumatin having particular organoleptic properties, and to processes for their manufacture.BACKGROUND OF THE INVENTION[0003]The consumer demand for sweet-tasting products appears ever-increasing. However, the traditional naturally-derived sweeteners, particularly sucrose, suffer from the major drawbacks that they are high in energy content (“high in Calories”), leading to a risk of obesity and associated health problems. They are also associated with tooth decay.[0004]There has hence been an enormous amount of work on developing synthetic sweetener...
